Which setup: 18-55 + 55-200 OR 18-135 ?

I'm looking to replicate my old setup which was a Nikon D600 with the 24-120 F/4 + 50 F/1.8 + 85 F/1.8. Right now I have the X-T1 with the 18-55 kit lens + 27 F/2.8 (and saving for the 56 F/1.2). Is anyone considering selling their 18-55 (or 18-55 + 55-200) to get the 18-135 instead?

I mainly do travel photos for fun and a couple of paid event jobs a year, so I like the idea of one zoom that stays on-camera most of the time. But the extra reach of the 55-200 at close to the same price is tempting.
